WATER-COOLED DOOR.

SPECIFICATION forming part of Letters Patent No. 712,678, dated November 4, 1902.

Application filed March 8, 1902. Serial No. 97,286. (No model.)

To ctZZ whom, it may concern:

Be it known that I, NICHOLAS HOUY, Jr., a citizen of the United States, residing at Munhall, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Water-Cooled Doors, of which improvement the following is a specification.

This invention relates to certain new and useful improvements in water-cooled doors for open-hearth furnaces or for use in connection with any form of furnaces that employ watercooled doors.

The object of my invention is to provide novel and effective means to save the waterpipe and prevent damage to the furnaces and, further, to permit the operation of the doors in case the latter should become sprung, so as to be out of true alinement.

Briefly described, the invention consists in making the pipe which feeds the water from the water-line to the water-cooled door in sections, telescoping one within the other; and the special construction by which I accomplish this will be hereinafter more specifically described and then particularly pointed out in the claim.

In describing the invention in detail reference is had to the accompanying drawings, forming-a part of this specification, and wherein like numerals of reference indicate like parts throughout the several views of the drawings, in which- Figure l is a front elevation of a pair of furnaces with my improved devicein position,

showing one of the doors closed and the other and prevent same from being burned out and In the accompanying.

rendered worthless.

illustration of my invention 1 represents a door of this form, usually arranged to slide in guides 2, suitably connected to the furnace 3. This door is hollow, and feeding into the same at the upper edge thereof is a pipe 4, which at its upper end is armed inwardly to form an interior flange or collar 5. Telescoping into this pipe 4 is a pipe 6, which at its upper end connects with the water-line 7 and at its lower end is formed with an annular exterior flange or collar 8, that engages with the collar or flange 5 on the pipe 4: when the pipes are fully extended, so as to prevent disengagement thereof. Communicating with the door 1, near the upper end thereof, isa pipe 9, that extends outwardly from the side of the door and downwardly, so as to telescope within a pipe 10, connected to the waste-water line or pipe 11. Doors of this nature are usually elevated by hydraulic pressure. I preferably construct these rods or links 12 in two parts, as shown, the lower sections being connected tothe door and the upper sections connected to the cross-head of the piston. This construction in event of the doors being sprung permits sufficient lateral movement of the rods to effect the raising of the doors.

\Vith the water-feeding pipe telescoped, as shown, it will be observed that the doors may be elevated or lowered without cutting off the water supply, thus constantly cooling the doors, and in the practice of the invention it will also be observed that various changes may be made in the details of construction without departing from the general spirit of my invention.

Having fully described my invention, What I claim as new, and desire to secure by Letters Patent, is

In a device of the type set forth, the combination with a horizontal water-line at the upper portion of the furnace, of doors formed hollow on the interior and operating in suitable guides provided therefor on the furnace, pipes depending from said water-line and rigidly secured thereto, the lower ends of the pipes carrying flanges, pipes having their lower ends extending into the said interior of the doors, and rigidly secured to the doors, and receiving said first-named pipes at their upper portions, the upper ends of said secondnamed pipes being bent inwardly to engage the exterior of the first-named pipes, a horizontal pipe at the lower portion of the fursigned'my name in the presence of two subnaee, upwardlyextending pipes carried by scribing witnesses.

said horizontal pipe, and outwardly and downwardly extending pipes carried by the doors NICHOLAS HOUY 5 extending into said last-named npwardly-ex- In presence oftending pipes, substantially as described. LOUIS MOESER,

In testimony whereof I have hereunto R. R. LOWREY.
